Micromeccanica Miniature High-Speed
Precision Drill

Very much smaller than it looks and made in Italy by the precision engineering company Micromeccanica, this  Type "Microtrapano RC50" miniature high-speed drill had all its rotating components balanced to ensure smooth running. As just 3 speeds of 2,000, 6,000 and 10,000 r.p.m. were provided, the machine was of limited general use and intended only for the drilling of tiny holes in components for such as the watch, clock, mechanical instrumentation and electronic trades. Power came from a continuously-rate single or three-phase 50 Watt motor running at 2900 r.p.m.
Instead of a spindle held within a sliding quill moved by rack-and-pinion gearing, on the Microtrapano rigidity was improved by building the spindle into the head casting - the whole assembly being moved up and down by a long handle protruding from the right-hand  face of the base casting.
